I am looking for two PhD students to start in August 2018 to be housed in either Biological Systems Engineering Department or School of Natural Resources. Funds are available to support each student for three years. The focus of the project is to quantify the current and future impact of the Eastern Red Cedar on water resources in the Nebraska Sandhills and Platte River. Though both students will be involved in all aspects of the project, the specific tasks for each student include the following:
One student will focus on quantifying the current extent of the Redcedar in the Sandhills by using high-resolution satellite images and developing a model to predict future encroachment. This will be accomplished by evaluating historical satellite images across Nebraska and identifying variables that impact the rate of Redcedar encroachment. Previous experience with GIS and remote sensing required.
The second student will model the study area using SWAT and MODFLOW to evaluate the impact of Redcedar encroachment on water resources in the Sandhills and ultimately the Platte River. Modeling experience with either SWAT or MODFLOW required.
